12 Volt Battery Replacement
Noticed yesterday after my Travel Trailer battery would not charge on the trickle charger for more than 3 days, the battery is over 10 years old. How often should the battery be changed, I am thinking...

If you camp mostly with electric hookups, then a single 12V deep cycle Marine/RV battery is all you need. If you frequent state/national parks without power or boondock, then paralleling two 12V batteries(still 12V) will almost double your runtimes without a genny. You can series two 6V golf cart batteries to get the needed 12V or parallel two pairs of 6V in series(four 6V batteries wired together to give 12V). The 6V golf cart batteries are more durable when it comes to deep discharges and charges.
My rig has two 12V batteries in parallel.
Here are some battery care facts:
Check the water levels frequently.
Use only distilled water when adding water. Minerals will shorten the life of it.
Letting the battery voltage drop below 12.00Vdc(50% charge state) will shorten the life of the battery.
Here is a 12v battery voltage State of Charge chart:
12.6+ = 100%
12.5 = 90%
12.42 = 80%
12.32 = 70%
12.20 = 60%
12.06 = 50%
11.9 = 40%
11.75 = 30%
11.58 = 20%
11.31 = 10%
10.5 = 0%
